re:tune
re:tune is a no-code platform for building GPT-powered chatbots and AI applications trained on your own website pages, files, plain text and YouTube videos, then published as an embeddable widget or through WhatsApp, Telegram and Messenger.
What is re:tune?
re:tune is a no-code SaaS platform for building AI applications and chatbots on top of GPT models. Its product pages describe it as the missing platform for building AI applications, and the keywords the site declares on its documentation route say the same thing in plainer terms: gpt-3, gpt-4, openai, generative ai, no-code ai, ai apps, fine-tuned model, custom chatgpt.
The central idea is a bot that knows your material. Each chatbot is trained through what re:tune calls embeddings, built from sources you supply: a crawl of your web pages, uploaded files, pasted plain text, question-and-answer pairs, or a YouTube video. Once trained, you choose where the bot lives — a customisable chat widget embedded on your site, a shareable link, or a messaging channel such as WhatsApp, Telegram, Messenger or SMS.
Around that core sit the features that make it commercially usable: human handover, so an agent can take over mid-conversation; conversation history and logs; lead capture for names, emails and phone numbers; the ability to lock a bot to a single domain; a custom opening message; thread resets; and API keys issued per bot. Workspaces keep chatbots, embeddings and keys apart, which matters for agencies handling several clients. Users can also bring their own OpenAI or OpenRouter API keys instead of routing model billing through the vendor. The publisher is Retune AI Inc., a Delaware corporation with a San Francisco address, and the contract is governed by California law.
One thing to know before visiting. The address retune.so no longer serves this platform. The root domain — and app.retune.so, the historical application subdomain — now show a different, unrelated product: a two-minute growth diagnostic built around the line find your growth constraint, whose sign-in button is disabled. The pages that document the chatbot platform are still online and still reachable directly: pricing, docs, roadmap, terms of service and privacy policy. Those pages are what this review describes. The legal documents have not moved since December 2023, the roadmap has stopped, and the login, about, contact and features routes all return 404. The publisher has announced nothing either way.
What it does
- Build a GPT-powered chatbot without writing any code
- Train it on your own material: crawl a website, upload files, paste plain text or question-and-answer pairs, add a YouTube video
- Capture visitor names, email addresses and phone numbers automatically
- Hand a live conversation over from the AI to a human agent
- Publish the bot as an embedded widget, a shareable link, or on WhatsApp, Telegram and Messenger
- Keep chatbots, embeddings and API keys separated by workspace
- Correct a wrong answer and have the bot retrained on the correction
When to use re:tune / When not to
A quick filter to help you decide if re:tune is the right fit.
When to use re:tune
- Non-technical teams that want a chatbot trained on their own content without writing a line of code
- Marketing and sales teams that capture and qualify leads, collecting name, email and phone before a human takes over
- Agencies running several clients at once, with separate workspaces, branding removal, white-label and a custom domain on the higher tiers
- Website owners who want an embeddable chat widget locked to the domain they own
- Support teams that want AI answers with a live handover to a human agent mid-conversation
When not to use re:tune
- European organisations that need documented GDPR compliance: it is an unshipped request on the public roadmap, never a claim made by the publisher
- Buyers who want a monthly plan, since only annual tiers are published, from USD 499 to USD 3,999 per year
- Teams that depend on responsive support, as there is no contact page, no form and a single email address for everything
- Workloads that need availability guarantees: the service is provided AS-IS, with no SLA and no security certification shown on the site
- Anyone who wants to test the product before paying, since no free trial and no priced free tier are documented
How to use re:tune
A typical end-to-end flow, from setup to results.
- Create an account from the pricing page, where every tier carries its own sign-up link
- Open a workspace, then create a chatbot inside it
- Build an embedding: crawl a URL or every link on a page, upload files, paste plain text or question-and-answer pairs, or add a YouTube video
- Attach the embedding to the bot, then set its opening message and input placeholder
- Add your own OpenAI or OpenRouter API key, either on the bot or on the workspace
- Turn on lead capture and pick the fields you need: name, email, phone
- Style the chat widget and restrict where it may be embedded to a domain you own
- Publish through the channel that fits: embedded widget, shareable link, WhatsApp, Telegram, Messenger or SMS
- Follow exchanges in the conversation history and logs, edit a wrong answer and let the bot retrain on it
- Expect to learn inside the app itself, as the documentation route renders client-side and is not readable outside a browser
Pros & Cons
Pros
- An unusually wide set of training sources for a no-code tool: site crawl, files, plain text, question-and-answer pairs and YouTube videos
- Many delivery channels actually shipped rather than promised: widget, shareable link, WhatsApp, Telegram, Messenger and SMS
- Human handover and lead capture are both delivered, which covers the commercial use case from first message to closed conversation
- Workspace isolation and per-bot API keys make multi-client work practical for agencies
- White-label and a custom domain are available on the top tier, branding removal one tier below
- The customer keeps ownership of their Customer Data under clause 4.1 of the terms
- You can bring your own OpenAI or OpenRouter key, avoiding a billing middleman, and the public voting roadmap carries a verifiable list of what shipped
Cons
- Strong signals that the product has been left alone: legal documents unchanged since December 2023, a frozen roadmap, and app.retune.so, the historical application subdomain, now serving an unrelated landing page
- The sign-in button on the current home page is disabled and the login route returns 404, so it is unclear whether a new account can still be opened
- GDPR compliance is never claimed; users asked for it repeatedly on the public roadmap and it was never shipped, and the DPA link resolves to the terms page instead of a DPA
- No security certification is displayed anywhere on the site — no SOC 2, no ISO 27001, no HIPAA — and no subprocessor is named, only categories of providers
- No contact page and no form: one email address covers support, legal and data protection, no official social account was found, and the documentation route only renders inside a browser
- Pricing is published annually only, from USD 499 per year; the monthly toggle requires an account, and the “Hobby” tier is cited as a baseline without ever being described or priced
- No free trial, only a 30-day money-back guarantee, and clause 2.5 states that no future feature is guaranteed to be delivered
Pricing & Plans
No free plan is documented. The pricing page cites a “Hobby” tier as a baseline — the Launch card reads “Everything in Hobby” — but no Hobby card, price or feature list appears anywhere, so the existence of a permanent free tier is not established. The lowest documented entry point is the Launch tier at USD 499 per year, followed by Grow at USD 999, Scale at USD 1,999 and Max at USD 3,999, all billed annually. A monthly/yearly toggle exists on the page but is rendered client-side, so monthly amounts are not public. Every tier carries a 30-day money-back guarantee, presented as a way to try the product for a month. The terms add that amounts are exclusive of tax, that late payment carries interest of 1% per month and that access may be suspended five days after the due date, and that 30 days’ notice is given before any price change.

Data, GDPR & hosting
A consolidated view of how re:tune handles your data.
GDPR overview
re:tune never claims GDPR compliance anywhere on its site. The word GDPR appears only in user requests on the public roadmap, none of which has been shipped. A Data Processing Addendum is incorporated by reference in clause 2.2(b) of the terms, but the link supplied points back at the terms page itself, so the DPA text cannot be read. The privacy policy does state legal bases — performance of the contract, legitimate interest, legal obligation and consent — and lists rights for EEA and California residents: access, copy, rectification, erasure, restriction and withdrawal of consent. International transfers are acknowledged, data being held in the United States and elsewhere. No Article 27 EU representative and no data protection officer are named, and no subprocessor list is published, only categories of providers. Every request goes through one address, support@retune.so. The policy is dated 20 December 2023.
Who owns the data?
The Terms of Service split ownership in two. Under clause 4.1 the customer exclusively owns all Customer Data and the insights produced for them, while Re:tune exclusively owns the service, its documentation and what it calls System Data — logs, statistics and metrics on performance, availability, integrity and security. Clause 4.2 goes further on feedback: any suggestion you send becomes freely usable by the publisher, with no compensation. The privacy policy adds that the personal data of your own end users is handled on your behalf, so you, not Re:tune, remain the party those people deal with when they exercise their rights.
Reuse rights
On the customer side the answer is simple: the data you upload or generate stays yours, and you may reuse it however you like without asking permission. On the publisher side, clause 4.3 grants a standing right to aggregate, collect and analyse Customer Data and information about how the service performs, and to use it to improve Re:tune’s products and services, during and after the contract. Anything disclosed to third parties must be aggregated and anonymised first. No opt-out is offered anywhere: the clause is unconditional and carries no end date. Neither the terms nor the privacy policy ever mention model training, which is why the question is best treated as unresolved rather than as a denial. Separately, the site itself runs third-party analytics (Google Analytics), advertising partners and tracking cookies, and automatically collects IP address, browser, operating system, country or state, device identifiers, pages viewed and time spent.
Data retention & training
Hosting summary
The privacy policy is the only source, and it says that information is maintained and processed by the publisher and its third-party service providers in the United States and elsewhere. That is as precise as it gets: no region, no data centre and no named provider, and no data-residency choice offered to customers. Cross-border transfers are treated as accepted through use of the service, with a general reference to applicable legal requirements rather than to a named transfer mechanism. As a technical indication only, the domain resolves to 35.192.204.40, an address operated by Google LLC (AS396982) in Council Bluffs, United States — that is infrastructure evidence, not a statement by the publisher. No subprocessor list is published either, only categories of providers such as billing, advertising, analytics, storage, security, consulting and legal services. A European buyer should treat United States hosting as the working assumption and ask for specifics in writing.
Things to keep in mind
Risks and trade-offs to weigh before adopting re:tune.
- Check that the service still accepts sign-ups before paying anything: the home page sign-in button is disabled and the login route returns 404
- The DPA link resolves to the terms page itself, so ask for the actual DPA text in writing before putting any personal data through the platform
- GDPR compliance is never claimed by the publisher, despite repeated user requests on the public roadmap
- The cheapest documented commitment is an annual one at USD 499, with no free trial to test the fit beforehand
- Clause 4.3 lets the publisher use customer data to improve its products with no time limit and no opt-out
- There is no SLA, the service is provided AS-IS, and the terms explicitly guarantee no future feature
- A bot trained by crawling your own site inherits whatever is wrong or out of date there, and it answers customers under your name, so keep reading the conversation logs instead of trusting the automation — all the more so when support runs through a single email address
Setup & Integrations
Technical difficulty
Low to moderate. The platform is positioned as no-code, so building and training a bot requires no programming. The real friction is elsewhere: you must supply your own OpenAI or OpenRouter API key, embed the widget through an iframe or script tag and configure the domain restriction yourself, and a custom domain with white-label is reserved for the top tier. Documentation adds to the effort, as the docs route only renders inside a browser. Users have also reported that one failing API key breaks every bot in the workspace, and that saved keys are never displayed again.

Should you pick re:tune?
On paper, re:tune is a complete product. The range of training sources is generous for a no-code tool, the delivery channels are numerous and shipped rather than promised, human handover and lead capture cover the commercial use case end to end, and workspaces, per-bot API keys, white-label and a custom domain make it workable for an agency. The customer keeps ownership of their data, and the public voting roadmap lets anyone check what was actually delivered.
The difficulty is not the feature list, it is the present state of the site. The legal documents have not been touched since December 2023, the roadmap has stopped moving, the sign-in button on the home page is disabled, and the historical application subdomain now serves an unrelated growth-diagnostic product. No shutdown has ever been announced, and we are not announcing one — but nothing on the site confirms that the platform is still taking customers either.
Add to that a high cost of entry. USD 499 per year is the cheapest documented plan, with no free trial and no free tier that can be verified, only a 30-day money-back guarantee. For a European buyer there are further blind spots: GDPR compliance is never claimed, the DPA link resolves to the terms page rather than to a DPA, and no subprocessor is named.
The sensible move, if the feature set matches a real need, is to write to the publisher’s single support address and obtain written confirmation that the platform is live and that new subscriptions are being served, before committing to an annual payment.
